Bernie Sanders is calling on Trump to end the Iran war as a way to lower gas prices. Gas prices have genuinely risen sharply since the conflict began in late February — the national average is up over a dollar per gallon according to multiple outlets. However, the analysis from OilPrice.com shows ending the war alone wouldn't guarantee sub-$3 prices because refining bottlenecks and supply chain disruptions are also major drivers. Trump's own response has been proposing a federal gas tax suspension, which would require congressional approval and still wouldn't fully offset the war-driven price increases.
